SWAB-HOLDER.

SPECIFICATION forming part of Letters Patent No. 778,848, dated January 3, 1905.

I Application filed June 4, 1902. Serial No. 110,244.

To all whom it may concern.-

Be it known that I, ADONIJAH B. ELLIOTT, residing at Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Swab-Holders, of which the following is a specification.

My invention has relation to swab-holders such as used in connection with rod-packing, more particularly piston-rod packing.

The object of my invention is to provide a simple, improved, and most efficient swabholder of the above character.

In the swab-holders of common construction the oil is fed solely through a top opening arranged immediately below the discharge of an oil-cup. In theory the oil is supposed to feed around the rod by means of the swab and to be applied thereto equally on all sides thereof. In practice, however, the feed is quite different and the result is objectionable, for it is found that while the upper portion of the rod may be sufiiciently lubricated the lower portion is insufiiciently lubricated and in many cases not lubricated at all, with injurious results.

My invention is designed to overcome the above objections by providing for efficient lubrication all around the rod.

The features of advantage and utility will be apparent from the description hereinafter given.

In the drawings, Figure 1 is an elevation of my improved swab-holder; Fig. 2, a section on line 2 2 of Fig. '1, and Fig. 3 a section on line 3 of Fig. 1.

In order to accommodate the present construction of piston-rod having enlarged hubs and ends, my swab-holder is made in two parts fitted over the rod and then fastened to the gland in usual manner. It will be understood, however, that my invention is applicable to both the single and two-piece swab-holder.

In the present instance my swab-holder comprises the two sections A and B, respectively provided with the attachinglugs a and 7) to receive the usual bolts for securing the holder to the gland. A suitable top opening may be provided, such as the opening A indicated C is arranged in the annular cavity of the holder, as shown in Fig. 2.

At the opposite sides of the swab-holders are formed openings B, the metal being extended upwardly and outwardly therearound, so as to form pockets or cups D, open at their tops and adapted to receive and hold a charge or supply of oil until taken up by the lower half or portion of the swab.

As indicated in the drawings and by preference, thetwo sections A and B of the swabholder are not made in halves; but the lower section B is made the larger and the cups 0r pockets D formed on the upper ends, with the result that pockets of considerable size may be here provided and the application of oil be made fairly high up on the sides of the swab. Moreover, oil that may be fed from the top opening would be less liable to ooze out through the joint between the two parts or sections of the swab-holder.

In practice the engineer in oiling up will insert the end or nose of his oil-can in these cups D and dischargea quantity of oil therein, which will be absorbed and carried down by the swab so as to thoroughly and efficiently lubricate the under portion of the rod. The usual oil-feeding devices will be sufficient to lubricate the upper portion of the rod, but not such under portion, as hereinbefore explained; hence the necessity and great utility of my construction, which makes the swab-holder most efficient in a simple manner.

The means for fastening the swab-holder to the gland form no part of my present invention, and, as a matter of fact, such holder may be fastened thereto in any suitable or desirable manner.

I claim-- 1. A swab-holder for rods comprising a holder proper having a continuous chamber around all sides of the rod and provided with a top oil-opening and with a side opening, a pocket formed adjacent such side opening and flared outwardly and upwardly, and a substantially continuous swab arranged in said chamber and exposed at said side opening for the purpose of receiving oil to assure lubriby the dotted lines in Fig. l. The usual swab l cation of the lower side of the rod.

2. A swab-holder for rods comprising a holder proper having a continuous chamber around all sides of the rod and provided with a top oil-opening and with two side openings, and a swab arranged in saidholder and around the rod, said holder having upwardly and outwardly flared cups or pockets around said side openings to receive oil to be fed to the lower portion of the swab below the rod.

3. A two-piece swab-holder for rods, comprising the sections A B, having a central opening to receive the rod, the line of division between such sections being located above the center of said opening, said holder having a top oil-opening A in the upper section A and also having side openings B near the upper ends of the lower sections B and pockets or cups D communicating with said openings B.

4. A two-piece swab-holder for rods comprising the sections A B having fastening-lugs a and Z2 respectively and also having a central opening to receive the rod, a swab arranged in said holder around the rod, said holder having a top oil-opening A in the upper section A and also having side openings B near the upper ends of the lower section B, and cups or pockets D connecting with said openings B and formed by extending the material of said section B upwardly and outwardly.

5. A swab-holder for a rod comprising a holder proper having a continuous chamber around all sides of the rod and having the usual top oil-opening, and in addition oil-openings at its opposite sides, in combination with a substantially continuous swab arranged in said chamber and around the rod, said holder having cups or pockets around said side openings to receive oil to be fed to the lower portion of the swab below the rod.

6. A swab-holder comprising the holder proper having a continuous chamber around all sides of the rod and having the usual top oil-opening and also having at opposite sides oil cups or pockets communicating with said chamber and arranged to receive oil to supply the lower portion of such chamber with oil, in combination with a swab arranged in said chamber and around the rod and exposed at said top oil-opening and at said oil-cups.

- 7 A substantially ring-shaped swab-holder formed in two parts, the lower one of which is the larger and provided at its upper ends with oil-openings and with surrounding cups or pockets therefor.

8. A substantially ring-shaped swab-holder having lateral side openings provided with pockets.
